I don't normally blog about anything, but I do follow quite a few and here they are:

Christopher Mills' fantastic writing is dedicated to the science fiction films and television series of the 1970s. I highly recommend it, because he captures the love that we all have of that era. If you grew up in the 70's and love science fiction, go there...like now.

Another great site that showcases the toys that we grew up with (including ads and lots of photos). I also dig the vintage catalog pages that he showcases (fashion mockery is awesome). Relive the 70's by taking a visit there and perusing the pages within. You won't regret it.
